Title: Alarm control unit
Inventor: SHORROCK STANLEY
IPC: G08B29/04
Filed: 1965-11-10
Abstract: 1,091,304. Intruder alarms. SHORROCK DEVELOPMENTS Ltd. Sept. 30, 1966 [Nov. 10, 1965], No. 47681/65. Heading G4N. An alarm control unit for a safe comprises a key-operated lock provided with a solenoid operated electromagnetic catch S which cannot be disengaged from the lock to allow rotation of the key from the non-alarm to the alarm position if the safe circuit has failed or is incomplete. If there is no fault, terminals N 1 , N 2  will be looped. On opening the lid of the control unit contact L will close to complete a circuit with battery B and a transistor T 1  will be conductive and will block transistor T 2  so that an alarm relay A is not energized, a green lamp G is lit and catch S is disengaged from the lock. Contacts K 1 , K 2  are changed over by rotating the key to set the alarm. Then if either of the connections between terminals N 1 , N 2  is broken transistor T 1  becomes blocked, transistor T 2  becomes conductive and relay A is energized to close contact A 2  and thus cause an alarm to be given. If the connections between terminals N 1 , N 2  are accidentally disconnected before the alarm is set so that transistor T 1  is blocked, transistor T 2  is conductive and relay A is energized to close contact A 1 , lifting of the lid will cause a red lamp R to light and the catch S is not disengaged from the lock so that the key cannot be turned to set the alarm. If the voltage of battery B falls below a certain level the catch S is not disengaged from the lock.

Title: Coil winding machine
IPC: H02K15/085
Filed: 1970-10-07
Abstract: 1332187 Winding stator cores W B WEIS 7 Oct 1970 [13 Oct 1969] 47724/70 Headings B3A and B3E A coil-winding machine comprises a rotary movement section in which a universal joint is rotated, an elliptical movement section including a needle bar 36 coupled by a pivoted rod 40 to the universal joint for translation of the rotary movement into an elliptical movement of a coil winding needle 42, the rotary movement section being coupled to the elliptical movement section so that moving them closer to or further from each other varies the needle swing by varying the effective length of the rod 40 and moving the radial distance of the universal joint with respect to the rotational axis of the rotary movement section varies the stroke of the needle. The swing (B) of the needle, Fig. 5 (not shown), corresponds to the minor axis of the ellipse and the stroke (A) corresponds to its major axis. A shaft 14 of the rotary movement section is driven by a motor 10 and the outer ring 26 of the universal joint is mounted pivot. ally on a clevis 24 secured to the shaft 14. The needle bar 36 is rigidly connected to the rod 40, which is located in a bushing 28 of the universal joint. Rotation of a handle 53 moves a housing 12 along slide bars 50, thereby moving the clevis relatively to the needle bar. To decrease the length of the minor axis (B) the clevis is moved away from the needle bar, so that the bushing 28 engages the rod 40 nearer its end, Fig. 6 (not shown), and hence further from the pivot axis of the bar. The length of the major axis (A) is varied by altering the rotary throw of the clevis, which is slotted and secured to a balance weight 22 on the shaft 14 by a bolt 58.
